chines, of which the following is a specification.

This invention relatesto improvements 1n twine-balling machines and the principal object of the invention is to provide means for giving the baller head mechanism a posltive drive when the cover is being placed on the ball.

Another object of the invention' isto utilize a portion ofthe above mentionedmeans as a weight for increasing the frictional engagement between the friction wheel and the cone.

This invention also consists in Lcertain othery features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of a balling machine Vprovided with my invention.

Fig. 2 is a section on line 2 2 of Fig. 1.

Fig. 3 is a longitudinal section through my improvement.

Fig. 4 is a view of the large gear wheel and its ratchet mechanism with the cover plate removed.

As is well understood the balling machine is provided with a baller head 1 which is arranged to swing on the arms 2 carried by the main frame of the machine. This head carries the spindle 3 upon which the ball of twine is formed. The twine is supplied to the spindle by the fly arms 4 carried by the hollow winding spindle 5 which is driven from the main drive shaft 6 by means of the belt 7 The twine is taken from the usual reel 8. The spindle 3 is rotated by means of the usual gears and shaft carried by the baller head and which are driven b the inclined shaft 9. Said inclined sha t carries the friction wheel 10 which is adapted to engage the cone 11 on the main shaft -part of the cone.

(i. The baller head is provided with the usual cam 12 which engages the projection 13 on the main frame and this cam acts to control the winding of the twine to properly form the ball. The cam is so formed that as it is slowly rotated it permits the baller head to swing downwardly. and inwardly and this means will cause the friction wheel l0 to slide toward the small end of the cone thus decreasing the rotation of the ball spindle as the size of the ball increases. When the baller head is in its lowest position the outer layers of twine are being placed upon the ball and these layers constitute what is known as a cover, this cover being fornieil with the Vfriction wheel engaging the small The object of the drive cone is to be able to adjust the speed while building the ball and'to secure a variable drive. The cover, however, requires one positive speed as it has been found that at this point in the formation of the ball the friction wheel is liable to slip on the small part of the cone without driving the ball spindle. It is the object of my invention to overcome this disadvantage and in carrying out my invention I` place a small bevel gear 14 on the main shaft 6 and a large bevel gear 15 on the inclined shaft 9. The teeth of these gears are slightly inclined so that they will properly gear with each other with the inclined shaft located to one side of the vertical plane of the drive shaft as it is necessary to so locate said inclined shaft on account of the arrangement of the parts in the baller head. The gear 15 has formed thereon a bushing 16 and this bushing passes through a bearing box 17. This box is slidably mounted in the forked part 18 of a bracket 19 ywhichis secured with the main frame. These parts are so arranged that as the friction wheel moves up the enlarged part of the cone said box will be raised olf its seat in the fork 18 and thus the weight of this box and the gear 15 will act to increase the frictional engagement of said wheel 10 with the cone. A recess 20 is formed in the front face of the gear 15 and the walls of this recess are provided with teeth 21. A dog carrying member 22 fits in said recess and this member is provided with a bushing 23 which projects from the recess and is keyed to the shaft 9. The dogs 24 are so arranged that they will permit the gear to revolve freely in one direction but in the other direction the dogs will engage with the teeth to lock the gear to the shaft. A cover plate is screwed to the face o'f the gear and holds the ratchet mechanism 4i-n position. The bushing 28 passes through an opening in this plate.

It Will thus be seen that when the friction Wheel is engaging with the large part of the cone the gear 15 Will be idling as it will be rotating faster than thev dog carrying lmember so that its `teeth Will simply slip over the dogs. As soon as the cam permits the baller head to drop down the friction Wheel will slide off the cone and then as the f inclined shaft 9 slows down the dogs will engage the ratchet teeth and thus the gear 14 will positively drive the inclined shaft through the ratchetmechanism and gear 15. In this Way a positive drive is given to the baller spindle to complete the formation of the ball thereon.

It is thoughtfrom the foregoing description that the advantages and novel features of my invention Will be readily apparent.

Y I desire it to be understood that I may make changes in the construction'an'd-in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claims.

What I claim is 1. The combination With the frictional drive of a balling machine, of automatic means for changing the frictional drive'to a positive drive .toward the end of the Winding operation, said means consisting of gearing connecting the main shaft With the driven shaft and ratchet mechanism associated with the gear onthe driven shaft.

2. The combination with the frictional drive of a ball form-ing machine including the main and driven shafts, of a beveled gear on the main shaftya beveled gear slidably mounted on the driven shaft and meshing With the before mentioned gear, a bearing box connected With said' second mentioned gear, means for slidably supporting said box, a dog carrying member slidably keyed to the shaft, dogs carried bythe said member and teeth on the sliding gear for engaging said dogs.

Intestimony whereof I affix m". signature.
